Regenerated pure keratin fiber from discarded feathers and its preparation method

Abstract

The invention discloses a regenerated pure keratin fiber from discarded feathers and a preparation method thereof, wherein, a preparation method of regenerated pure keratin fibers from discarded feathers comprises: treating discarded feathers with high-temperature flash explosion, and then treating them with urea to obtain Feather keratin; dissolving the feather keratin, adding an antibacterial agent while dissolving; adding sodium cetylsulfonate, aging, and heating to obtain a spinning solution; using the spinning solution to prepare regenerated keratin fibers. The invention adopts high-temperature flash explosion and low-concentration urea synergistic treatment method to obtain waste feather keratin with excellent molecular weight and yield, and develops high value-added antibacterial regenerated keratin fiber on this basis, and develops sodium carbonate-sodium bicarbonate-ten A new solvent system of sodium hexaalkylsulfonate for improved spinnability of keratin solutions.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a pure keratin fiber regenerated from discarded feathers and a preparation method thereof. Background technique [0002] As a natural protein, keratin has very good biocompatibility and cell affinity, has certain mechanical properties, and can be processed. It will have a good development prospect as a textile material. The development and utilization of keratin materials is gradually unfolding, and has gradually moved from primary utilization to the application of degradable and renewable materials. In terms of fibers, pure keratin fibers or composite keratin fibers can be developed; in terms of textiles, home textile fabrics and medical materials can be developed. Discarded feather keratin, as a natural polymer material, is not only rich in sources and low in price, but also has good special properties and has a good development prospect. [0003] As a biomacromo...

However, research in this field has not yet been maturely reported

[0005] In short, the research and application of exploring efficient keratin extraction methods has become a current hotspot. However, due to the complexity of the structure of discarded feathers, the current extraction methods are still unable to obtain keratin with molecular weight and yield that meet the requirements. Based on the keratin The antibacterial pure protein fiber has not been reported yet
